OK finally got the kahunas to try it myself. Flush mounting the DVD's bezel in the stock bezel. Took me about 5 hours to get to this point, still have final filling, sanding and painting to do. Tools: dremel with cutoff disk, epoxy, spot putty filler and pad sander.
Premodified stock non-nav bezel
DVD's bezel to be flushed in with bottom trimmed to fit over the top of the A/C controls
DVD Bezel lined up for the cuts.
DVD Bezel superglued in, dang compuound curves.
First sanding with the "ears" expoxied in
Nasty gaps due to cutting a lil big and compound curves.
Remember the old school way of body working called "leading". Took some scrap plastic, lit it with a lighter and then pushed the melted plastic in to fill the gaps.
sanded after using plastic weld.
And the state it is in now waiting for the spot putty filler to dry and the backside of the DVD bezel loaded with expoy on the backside for extra strength.
Day of final sandings and filling, going to use this textured black paint that I found at the local home center. After I find some filler primer that is plastic friendly. More to come!
